Here's how Cadillac made its Magnetic Ride Control suspension quicker and smarter

Bugatti makes the world's fastest car, but Cadillac claims it has developed the world's fastest suspension. Its fourth-generation Magnetic Ride Control technology receives hardware and software tweaks to deliver a more comfortable ride and sharper handling. It's offered on some variants of the CT4, CT5 and the Escalade. Introduced in 2002 on the Seville STS, this self-adjusting suspension is not as complicated as it might sound. It relies primarily on electromagnets that emit a magnetic field, and a magnetorheological fluid whose viscosity changes depending on the strength of the magnetic force. Sensors scan the road up to 1,000 times per second and send the information they gather to the electromagnets, which then alter their magnetic field as needed to modify the fluid's viscosity. The fluid is in the shocks, so making it thicker returns a firmer ride, and vice versa. In simpler terms, Magnetic Ride Control leverages chemistry and physics to make the ride sporty, comfortable, or somewhere in between -- all in the blink of an eye. By reacting to the changing magnetic field, the fluid-filled shocks filter out road imperfections and maximize tire contact with the road to deliver more precise handling. Cadillac began developing the fourth-generation system by improving the hardware. The in-wheel accelerometers are more accurate than before, the inertial measurement unit is more precise, and the damper fluid formula was changed for quicker response times and a smoother ride. Engineers then turned their attention to the system's software. They notably gave the sensors the ability to process a wider selection of input and output signals, which translates to a wider spread between comfort and sport. And, they made the response time up to 45-percent quicker. All told, the fourth-generation Magnetic Ride Control technology performs better under heavy braking and hard cornering, it delivers more consistent performance, and it reads the road more accurately. Cadillac proudly notes these are the most comprehensive updates it has made to the system in nearly two decades. Magnetic Ride Control comes standard on the 2021 CT4-V and the 2021 CT5-V, and it's bundled into the CT5's V Performance package, which also includes a mechanical limited-slip differential. It's also standard on the Sport and Platinum variants of the 2021 Escalade, and it's part of the Premium Luxury trim's Performance package.

Cadillac is returning to endurance racing with a new prototype in 2017

In two months, Cadillac will return to top-tier endurance racing with its all-new Daytona Prototype International racecar after 14 years away. The car, which adheres to IMSA's new DPi regulations, looks as long, low, and Cadillac-like as anyone could have hoped. It's set to debut at the Rolex 24 at Daytona and will compete head to head with the likes of Mazda and Nissan in what is shaping up to be one of the most diverse and exciting forms of American motor racing in years. The new car will be run by Wayne Taylor Racing, the team that previously fielded the Corvette Daytona Prototype. Wayne Taylor himself has won the 24 Hours of Daytona twice, in 1996 and 2005. He now manages the team and leaves the driving duties to his two sons, Ricky and Jordan. They'll be joined in the cockpit by Max Angelelli, Wayne Taylor's teammate in 2002 at Cadillac's last unsuccessful attempt at endurance racing. To understand Cadillac's new car, officially called the DPi-V.R., you need to understand IMSA's DPi category. Basically, manufacturers are allowed to base their car on one of four chassis that follow the FIA LMP2 regulations. The chassis come from either Dallara, Onroak Automotive, ORECA or Riley/Multimatic. Cadillac will base their car on the Dallara platform. The DPi regulation differ from the LMP2 in two major ways: non-standardized engines and the ability to change certain parts of the bodywork. The DPi regulations are intended to give the variety of the top-tier LMP1 cars at a fraction of the cost. When it came to choosing an engine, Cadillac wanted to power the new car with something kinda sorta production based. The new car will use a naturally aspirated 6.2-liter pushrod V8 that shares some base architecture with the engine in the current CTS-V. While the power output hasn't been announced, expect about 600 horsepower. While that's down compared to the CTS-V, there is far less mass to move around as the Dallara chassis is a svelte 2,050 lbs. Since all the teams will be running different engine configurations, expect restrictors of some sort to help balance the power disparity. The parts of the body work that can be modified - The nose, sidepods, rear wheel arches and rear valance - have all been designed to mimic Cadillac roadcar design elements. Even the wheels look like they were pulled straight from the CTS-V. The front splitter, the floor, and the diffuser are common elements shared with other DPi cars.

2020 Cadillac XT6 Sport Drivers' Notes | We have many mixed opinions

The 2020 Cadillac XT6 is Cadillac’s long-awaited answer to the numerous three-row luxury crossovers that have been on sale for years. It is not a shrunken Escalade. Instead, GM decided to pull one of its other well-used platforms for duty, with the XT6 being most similar to the GMC Acadia underneath. That means the Cadillac is rolling with similar running gear, too. Under the hood is a 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque, mated to a nine-speed automatic transmission. Front-wheel drive is standard, but our Sport model has an upgraded all-wheel-drive system. It also has some other special mechanical bits to make it better than the standard XT6. For example, the Sport trim has continuously variable dampers that stiffen in Sport mode. That upgraded all-wheel drive system adds twin clutches on the axles to facilitate torque vectoring. And the steering ratio is changed to 15:1, as opposed to the 16:1 ratio used on Premium Luxury trim models. This XT6 Sport also features some exterior and interior finishes not seen on other XT6 models. Black trim dominates outside, headlined by a large, black mesh grille. Then on the inside, we get real carbon fiber trim. There are plenty of cool features like CadillacÂ’s Night Vision and the rear camera mirror, but Super Cruise still isnÂ’t available as an option on this Cadillac. GM has promised a wider adoption of Super Cruise for its lineup in the future, but weÂ’re not there yet. Before options, our XT6 Sport came in at $58,090, including the $995 destination charge. The $3,700 Platinum package adds semi-aniline leather seats, a suede headliner and premium carpeting throughout the cabin. A $2,350 Enhanced Visibility and Tech package brings us the eight-inch instrument cluster digital display, a head-up display, rear camera mirror, rear pedestrian alert and an automatic parking assist feature. Then, a $1,300 Driver Assist package adds adaptive cruise control and enhanced automatic emergency braking, including rear braking. Our car also has the $750 Comfort and Air Quality package, which adds heated rear seats, cooled front seats and an air ionizer for the cabin. The pretty Red Horizon Tintcoat costs $1,225, and the fancy Night Vision option adds another $2,000. That brings us to our grand total of $71,190.
